We have an over-zealous plans reviewer worried about the in-building riser sweep we use to transition from UG to OH. We’ve spent 2 man-hours to account for a .03 PSI pressure differential. But righteousness has prevailed and we can add a node and document the sweep now, so our plans reviewer should be able to sleep for the rest of the week. I’m embarrassed at our sloppiness, using 140 for 10 critical feet of pipe and whatnot.
This is why Chapter 17 of my great novel is tentatively titled “Why Stevie Drinks”.

I was going to guess foam concentrate piping but I think that requires Darcy instead of Hazen whereby you would need the friction factor instead of the c-factor... So, uhhh????
